 ### Changed
 
+- we deleted the `Default bibliography mode` in the Preference/General tab since it is a redundant setting. [#6470](https://github.com/JabRef/jabref/issues/6470)
 - We improved the arXiv fetcher. Now it should find entries even more reliably and does no longer include the version (e.g `v1`) in the `eprint` field. [forum#1941](https://discourse.jabref.org/t/remove-version-in-arxiv-import/1941)
 - We moved the group search bar and the button "New group" from bottom to top position to make it more prominent. [#6112](https://github.com/JabRef/jabref/pull/6112)
 - When JabRef finds a `.sav` file without changes, there is no dialog asking for acceptance of changes anymore.
